Nick,I am sure there would be many people interested. We will be interested to include a make.inc.arm file in the magma distribution and add CARMA as one more device supported. Some tuning may be needed, e.g., at first just to tune the block sizes in control/get_nb.cpp.Stan

Sounds good, glad to hear that I can help document this. I currently have everything compiling nicely but I'm having to play with the order of the libraries to fix some linker errors. Once that's done I'll use the test files to verify the function.

I got everything compiled for ARM last night. Give me the weekend to play with the test files on the CARMA board and write up the instructions. There wasn't any unforeseen changes to the make.inc but there were some flags I had to add in other makefiles.

Unfortunately I didn't have time to run any tests this weekend like I had hoped. Regardless here are the instructions for those who want to get started. Please note that I'm writing this assuming that you have cross-compiled for the CARMA kit before. If not I recommend this blog to get started: http://cudamusing.blogspot.com/.

-Download and save armel versions of lapack and blas from launchpad.com (CARMA users: be sure to use libraries for the Natty distro). You will point to these in your make.inc file.

-CARMA USERS ONLY: Apparently SECO didn't add the cuda/src directory to their version of the CUDA toolkit so I just downloaded the contents of that folder from the normal NVIDIA version and saved it in my CUDA directory

-CARMA USERS ONLY: Open the Makefile.internal file and change the -Dmagma_devptr_t flag to equal "integer(kind=4)". In the same file on line 41 (NVOPTS +=...) add the following flags: "-arch sm_21 -target-cpu-arch ARM --compiler-bindir /usr/bin/arm-linux-gnueabi-gcc-4.5 -m32"

-CARMA USERS ONLY: Open the CMakeLists.txt file and change the -Dmagma_devptr_t flag to equal "integer(kind=4)".

And I think that's all that I changed... It was over a few days of trial and error so please let me know if there was anything that I missed for those that are trying to compile.

Attached is my make.inc file for everyone look at. Again, I haven't tested anything yet so there's no guarantee that everything will work, but it will compile.
